Answer:
a = 2.5 m/s²
Explanation:
given,
initial speed = 0 m/s
final speed = 25 m/s
time = 10 s
acceleration of bike is equal to change in velocity per unit time
a = 2.5 m/s²
hence, acceleration of bike is equal to a = 2.5 m/s²
Answer:
Sometimes
Explanation:
Sometimes meaning in occasions. If it is a "vampire star" not likely because they also cause they also make novas happen by sucking the gas from another star.
Answer:
manufacturing cost = $16.5 q₂ + $1 q₁ - $ 5
Explanation:
given,
one unit price of first good is = $ 1000
one unit price of second good is = $ 16500
quantity of the first good = q₁
quantity of the second good = q₂
total cost to the manufacturer = $ 5000
revenue from good one = $1000 q₁
revenue from second good = $16500 q₂
manufacturing cost = total revenue - total manufacturing cost
manufacturing cost = $16500 q₂ + $1000 q₁ - $ 5000
but in the question we have to answer in thousands of dollar
so, divide the result by 1000
manufacturing cost = $16.5 q₂ + $1 q₁ - $ 5
Answer:
m₁ / m₂ = 1.3
Explanation:
We can work this problem with the moment, the system is formed by the two particles
The moment is conserved, to simulate the system the particles initially move with a moment and suppose a shock where the particular that, without speed, this determines that if you center, you should be stationary, which creates a moment equal to zero
p₀o = m₁ v₁ + m₂ v₂
pf = 0
m₁ v₁ + m₂ v₂ = 0
m₁ / m₂ = -v₂ / v₁
m₁ / m₂= - (-6.2) / 4.7
m₁ / m₂ = 1.3
Another way to solve this exercise is to use the mass center relationship
Xcm = 1/M (m₁ x₁ + m₂ x₂)
We derive from time
Vcm = 1/M (m₁ v₁ + m₂v₂)
As they say the velocity of the center of zero masses
0 = 1/M (m₁ v₁ + m₂v₂)
m₁ v₁ + m₂v₂ = 0
m₁ / m₂ = -v₂ / v₁
m₁ / m₂ = 1.3
Answer:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
Newton's First Law of Motion is also known as Law of Inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
The inertia of an object such as a truck is greatly dependent or influenced by its mass; the higher quantity of matter in a trailer, the greater will be its tendency to continuously remain at rest.
In conclusion, inertia is applicable to all physical objects.
